COOLING TABLE FOR GLASS-MOLDS.

SPECIFICATION forming part of Letters Patent No. 602,399, dated April 12, 1898. Application filed July16, 1897. Serial No. 644,756. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM HALEY, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Cooling-Tables for Glass-Molds and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others '10 skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in cooling-tables for use in conjunction with glass-presses; and it consists in the novel features of construction, combination, and

arrangement hereinafter described, and specifically pointed outin the claims.

The object of the invention is to increase the facility and speed of operation of the glass-press and of the manipulations necessary and incident to its operation, as will be hereinafter fully explained.

Figure 1 represents in side elevation a cooling-table constructed according to my inven- 2 5 tion. Fig. 2 represents the same in end elevation, partly broken away. Fig. 3 is a bottom View of the blast device 0. Fig. 4 is a top plan View of the table with the blast device broken away. Fig. 5 is a plan view of a 0 table exhibiting a modification of the structure adapted to carry the molds in a direct line, and Fig. 6 is a sectional view of the structure shown in Fig. 5.

My cooling-table comprises, essentially, a

3 5 movable surface on which the molds are carried while cooling, the same being preferably provided with ledges or stops to guide the placing of the molds and to insure their being placed accurately beneath the blast, means 0 for moving the mold-carrying surface, so as to bring the molds successively into the proper relation with the press to enable them to be easily and quickly transferred to the press,

and means for delivering a blast of air or other cooling medium upon the molds while on the table, and there is preferably combined with the foregoing essential elements means for receiving the molds after pressing and for receiving the pressed article, and

the whole is preferably, but not necessarily,

mount-ed on a truck for'facility of transportation.

In the drawings, A represents the fixed bed or top of the table; A, its supporting-frame;

a a, the truck-Wheels; a a side bars for strengthening the frame; a the bottom bars, forming axles for the wheels. In an opening in the fixed top A is arranged the movable mold-carrying table or surface B, preferably having on its surface ledges or stops 5 b to facilitate the proper placing of the molds R.

0 represents an air-blast comprising a tubular chamber conforming in shape to the surface on which the molds are carried and provided with nipples c c, by which it may 6 be connected in any suitable manner, as by a hose, to a source of air-pressure, such as a blower or other air-forcing device. (Not shown.) On its under side the air-blast O is provided with numerous openings 0 through 0 which a continuous blast of air is emitted upon all the molds on the table or surface B and by which they are most perfectly and efficiently cooled to the precise degree required.

The preferred means for moving the molds 7 5 successively to the point whence they are transferred to the press is by rotating the table B, although it is obvious that the molds could equally well be moved in a direct line, as by the mechanism shown in Figs. 5 and 6. To effect the rotation of the table 15, it is supported on a strong center pin D, which is sleeved in a bearing d, supported by the rigid top A or by the table-frame, and the pin D is adj ustably supported at the bottom bya screw- 8 center d threaded through the bearing-sleeve d, by which means the revolving top B may be adjusted to the exact level of the fixed top A. WVhen the rotating form is employed, the ledges b are preferably so formed as to constitute recesses 19, (best seen in Fig. 4,) which each receive a mold, and adjustingscrews 12 are threaded through the ledges b and serve to regulate the posit-ion of the mold, so that when placed against the screw 12 the mold shall be always directly beneath the airblas't O whatever be the size of the mold. The ledges b on the rotating table B are undercut at their outer portion, as seen at b in Fig. 1, and a stop 6 is secured to the fixed top 1oo jj, passing through the slots.

A of the table in such position that it projects in the path traversed by the undercut portion of the ledges b. When the recesses 19 are empty, the table B rotates freely, but if a mold is in any of the recesses it abuts against the stop e when it reaches that point, and the further rotation of the table is prevented until the mold is removed.

Vhen the direct-moving surface is employed, it is preferably arranged as an endless belt or sprocket-band B, (see Figs. 5 and 6,) which travels in a depression or opening 12 of the table A and is actuated by the drums or sprockets as, which are driven by the gears 71 o from any suitable source of power-for instance, from the shaft of the glass-press with which the table is used, in which case the shaft 0 could be merely an extension of one of the shafts of the press. The band or apron B is supported by the bed A which may be integral with or separate from the bed A and is so adjusted that the top of table A and band B are in the same plane, so that the molds R B may be readily slid from one to the other. On the band or apron B the ledges b may be dispensed with or, if used, may be short bars or blocks, as indicated in dotted lines, and the table Amay be notched, as indicated at z in Fig. 5, to allow them to pass, the stop 0 being of course dispensed with. Obviously the gears n 0 could be omitted and the band B moved by hand, as table B is designed to be.

At one side of the table is attached a projecting leaf F, flush with the top A of the table, and which when the table is in use rests upon a ledge g on the press-bed G, so as to bring the top of the press-bed, the leaf F, the top A, and the top of the table B in the same place, so that no obstruction is offered to the sliding of the mold from the table B to the press-bed. A removable shelf H is adjustably supported at the end of the bed A, preferably at a slightly lower level, upon which the molded article is emptied from the mold, and this shelf has at one end a rabbet h deep enough to receive the plate or shovel on which the molded articles are transferred to the finishing-table or annealing-oven, as the case may be. To enable the shelf 11 to be adjusted for height, the bars a which support it, may be slotted, as seen at 2' in Fig. l, and secured to the frame A by bolts, as In a similar manner the frame A may be made adj ustable for height by constructing the uprights a in two parts, as shown in Fig. 2, one part, as a", being slotted and secured to the other part by bolts, as 7c.

mold is placed when taken from the press, so as to emit a blast upon the mold before it is opened and emptied.

The operation is as follows: Assuming that the cooling-table has been adjusted to the press and secured in position, the air-blast connections made, and the recesses on table B supplied with molds, the pressman takes the mold which rests in the recess next to the stop e, slides it on the press-bed and into position under the plunger. The gatherer fills the mold with molten glass, the plunger descends and forms the article, and as the plunger rises the pressman slides the mold on the table A in reach of an assistant and takes from the table B another mold which has meantime come to the stop e and proceeds as before. The assistant takes the mold delivered to him, opens and empties it, and places it upon table B in the vacant recess and at the same time rotates the table so as to bring a mold against the stop 6, and thus the work proceeds indefinitely. By always rotating the table B in the same direction (indicated by the arrow in Fig. 3) the idle molds are subjected to the cooling-blast during the time required to mold as many articles as there are molds upon the table B. I have shown the table B provided with five of the recesses d, but any number may be used, and it is obvious that the table can be used with a less number of molds than recesses, if desired. The operation is precisely the same with belt B as with the rotating table B, the assistant moving the belt one space each time he places a mold upon it.
